XMPP is an open-standard communications protocol for message-oriented middleware based on XML (originally named
Jabber). Prerequisites:
- XMPP domain: dev.local
- ejabberd server name: im1.dev.local
- Administrative account: admin@dev.local
In order to install the
ejabberd IM server in Debian:
apt-get -y install ejabberd
Add administrative account (user, host, password):
ejabberdctl register admin dev.local P@ssw0rd
Configuration
You will need a certificate file for your domain. While obtaining self signed certificate, please ensure:
- Common Name is the XMPP domain name, e.g. dev.local.
- Resulting pem file has both key and certificate
Take a look how to can create a self signed certificate
here and add it to trusted certificates
here.
All configuration is stored in
/etc/ejabberd/ejabberd.cfg file.
%% Admin user
{acl, admin, {user, "", "dev.local"}}.
%% Hostname (The list of domains we are going to serve)
{hosts, ["dev.local"]}.
...
%% domain_certfile: Specify a different certificate for
%% each served hostname .
{domain_certfile, "dev.local", "/etc/ejabberd/dev.local.pem"}.
...
%% To enable in-band registration, replace 'deny' with
%% 'allow'. This let users create IM account from theirs
%% client applications.
{access, register, [{allow, all}]}.
XMPP DNS Discovery
You need to add the following records to your dns server:
$ORIGIN _tcp.dev.local.
$TTL 900 ; 15 minutes
_jabber SRV 5 0 5269 im1.dev.local.
_xmpp-client SRV 5 0 5222 im1.dev.local.
_xmpp-server SRV 5 0 5269 im1.dev.local.
